KB5050094 is a non-security preview cumulative update for Windows 11 version 24H2 that advances the operating system to build 26100.3037. It combines gradual-rollout features with fixes for File Explorer, audio, gaming, cameras, sign-in, networking and other Windows components. Microsoft’s support page is headed January 28, 2025, while its Remote Desktop known-issue text separately describes KB5050094 as released January 21, 2025.
What is KB5050094?
Microsoft classifies KB5050094 as a non-security update containing quality improvements for Windows 11 version 24H2, all editions. Installing it brings the operating system to build 26100.3037. The support article also lists servicing stack update KB5050108, build 26100.3023. Microsoft describes the package as a preview, rather than a security update.
The update’s items are divided into gradual rollout and normal rollout. Gradual rollout means Microsoft may make an item available over time, so it might not appear on every eligible device immediately. Normal rollout items are not marked with that gradual-availability caveat in the support article. See Microsoft’s KB5050094 support article for the complete release notes and current package guidance.
What changes and fixes does KB5050094 include?
Gradual rollout: features and fixes
- Taskbar: Improved hover previews and their animations.
- Chinese font support: Added Simsun-ExtG, with 9,753 ideographs: 4,939 in Unicode range G (30000–3134A), 4,192 in range H (31350–323AF), and 622 in range I (2EBF0–2EE5D), according to Microsoft’s release notes.
- File Explorer: Added a New Folder command to the context menu in the left pane and options affecting restoration of open tabs and restartable apps. Fixes address repeated searches, file date or time properties changing after copying, theme icons in the details pane, and search-box focus.
- Settings: Allows time-zone changes without administrator rights.
- Mouse and input: Fixes mouse disappearance, transparency and stutter problems, as well as a Pinyin IME language-switching issue.
- Display and apps: Fixes Snipping Tool distortion across monitors with different scaling and Excel 2016 files getting stuck on the loading screen.
- Gaming and system reliability: Fixes Game Bar recording error 0x82323673, a domain-join failure, slow Task Manager closure, a Dam.sys watchdog timeout on resume, and cumulative update installation error 0x800736b3 after a feature-on-demand installation failure.
Normal rollout: fixes
- HDR gaming: Addresses oversaturated colors in games using Auto HDR.
- Audio: Addresses USB audio devices stopping work, particularly devices using USB 1.0-based DAC drivers, and external audio management devices reporting Code 10.
- Pinyin IME search: Stops Bing automatic suggestions from appearing in the search box for search-engine sites such as Baidu. Manual suggestions remain available with Ctrl+Tab or the chevron.
- USB cameras: Fixes an issue in which cameras could fail to be recognized as on after the January security update.
- Passkeys and shutdown: Removes a one-minute timeout when using a passkey on a phone and addresses slower shutdown when a controller is connected.
- Wi-Fi sign-in: Fixes the Windows Security dialog becoming unresponsive when signing in to certain Wi-Fi networks.
- Other changes: Addresses a memory leak when predictive input ideas appear, adds drivers to the vulnerable-driver blocklist, and fixes a Remote Desktop Gateway sign-in or error problem when device redirection is enforced.
Known issues and later resolutions
Microsoft’s issue notes describe specific configurations and update sequences; they do not mean every Windows 11 24H2 device is affected.
#1 Best Overall
- 1.1 GHz (boost up to 2.4GHz) Intel Celeron N5030 Quad-Core
Roblox on Arm devices
Microsoft reported that players using Arm devices might be unable to download and play Roblox from the Microsoft Store. Its listed workaround is to download Roblox directly from Roblox.com; Microsoft directs users to Roblox support for updates.
OpenSSH service startup
Some customers reported that the OpenSSH service failed to start after the October 2024 security update, blocking SSH connections and requiring manual intervention to run sshd.exe. Microsoft said the issue affected a limited number of enterprise, IoT and education devices and was addressed in KB5052093.
Rank #2
- 256 GB SSD of storage.
- Multitasking is easy with 16GB of RAM
- Equipped with a blazing fast Core i5 2.00 GHz processor.
Citrix Session Recording Agent
Devices running Citrix Session Recording Agent (SRA) version 2411 could revert the January 2025 security update when restarting. Microsoft said home users were not expected to be affected. Citrix resolved the issue in SRA version 2503, released April 28, 2025, and later versions.
Remote Desktop sessions freezing or disconnecting
Microsoft reported that sessions on Windows 11 24H2 could freeze shortly after connecting following KB5050094 and later updates, leaving the keyboard and mouse unresponsive until the user disconnected and reconnected. Microsoft says KB5052093 addresses that issue.
Rank #3
- 14" diagonal, 1366x768 resolution, HD BrightView LED, Glossy NON-TOUCH Display
A separate issue involved unexpected RDP or Remote Desktop Services (RDS) disconnections. Microsoft described UDP-based connections from Windows 11 24H2 devices to RDS deployments on Windows Server 2016 or earlier disconnecting after 65 seconds. Reports rose significantly after the March 2025 security update KB5053598. Microsoft says KB5053656 addresses the disconnection issue. For enterprise devices on earlier updates, its article describes a special Known Issue Rollback Group Policy and a restart.
How to get KB5050094
Microsoft’s original instructions offered the update through Windows Update under Optional updates available. The page marked Business availability as “No” and said the changes would be included in the next security update for Windows Update for Business. It also listed Microsoft Update Catalog availability and said WSUS administrators could import the update manually.

For the Catalog or command-line route, Microsoft described a package containing one or more MSU files. Its historical instructions say to place all KB5050094 MSU files in one folder for DISM installation, or install individual files in this order: KB5043080, then KB5050094. Because package contents and deployment instructions can change, administrators should consult the live Microsoft support article for the applicable files and exact DISM or PowerShell commands, including instructions for running systems and mounted images.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Can you uninstall KB5050094?
Microsoft notes that WUSA’s /uninstall switch does not work for the combined SSU/LCU package because the servicing stack update (SSU) cannot be removed from the system. The release notes say the cumulative update (LCU) can be removed with DISM’s /Remove-Package option using the package name. Follow Microsoft’s current instructions for the affected system rather than treating the combined package as a single, wholly removable update.
